RECYCLE CONTENT ORGANIC ACIDS FROM ALKOXY CARBONYLATION
Recycle content organic acids, such as recycle content propionic acid and recycle content butyric acid, are produced using a process and system that applies physical and/or credit-based recycle content from one or more feed materials to the organic acids produced from the feed materials. Thus, recycle content organic acids may be produced that contain physical recycle content and/or credit-based recycle content.

(c) gasifying at least a portion of the pyrolysis effluent to form a recycle content syngas;
(d) optionally forming a recycle content C1-C6 alkanol with at least a portion of the recycle content syngas;
(e) optionally forming a recycle content carbon monoxide with at least a portion of the recycle content syngas;
(f) optionally forming a third recycle content ethylene and/or a third recycle content propylene with at least a portion of the recycle content C1-C6 alkanol; and
(g) reacting ethylene and/or propylene with a C1-C6 alkanol, water, and carbon monoxide in the presence of a catalyst system to thereby produce a recycle content organic acid, wherein the recycle content organic acid comprises recycle content from one or more of the following source materials—

11 . The process according to claim 10 , wherein the recycle content organic acid comprises physical recycle content from one or more of the source materials.
12 . The process according to claim 9 , wherein the reacting is carried out at a carbonylation facility, wherein at least one of the source materials providing recycle content to the recycle content organic acid is produced in a co-located source facility that is located within 10, within 5, or within 2 miles from the carbonylation facility.
13 . A process for producing a recycle content organic acid, the process comprising:
(a) treating a waste plastic to obtain, optionally through one or more intermediate processes, a recycle content ethylene, a recycle content propylene, a recycle content carbon monoxide, a recycle content methanol, or a combination thereof; and
(b) reacting ethylene and/or propylene with a C1-C6 alkanol, water, and carbon monoxide in the presence of a catalyst system to thereby produce a recycle content organic acid, wherein at least a portion of the ethylene, the propylene, the C1-C6 alkanol, or the carbon monoxide comprises the recycle content ethylene, the recycle content propylene, the recycle content methanol, or the recycle content carbon monoxide, respectively.
